Regression lines for differently-sized groups on the same plot
Hi there,
I've looked through the very helpful advice about adding fitted lines to
plots in the r-help archive, and can't find a post where someone has offered
a solution for my specific problem. I need to plot logistic regression fits
from three differently-sized data subsets on a plot of the entire dataset.
A description and code are below:

(no subject)
Dear all,
Can anyone take a look at my program below?
There are two functions: f1 (lambda,z,p1) and f2(p1,cl, cu).
I fixed p1=0.15 for both functions. For any fixed value of lambda (between
0.01 and 0.99),
I solve f1(p1=0.15, lambda=lambda, z)=0 for the corresponding cl and cu
values.
Then I plug the calculated cl and cu back into the function f2.
Eventually, I want to find the lambda value

mixing different modes of lty line type specification in legend() ?
Hi List,
is sth. like the following possible:
legend(x,y,c("A","B","C"), lty=list(1,"42","11")) ?
Or: is there a possibility to define a solid line using the "string" mode for lty?
Thanks
Marcus

question about solving equation using bisection method
Hi all,
I have the following two function f1 and f2.
f1 <- function(lambda,z,p1){
lambda*(p1*exp(-3*z-9/2)+(0.2-p1)*exp(4*z-8))-(1-lambda)*0.8}
f2 <- function(p1,cl, cu){
0.8*(pnorm(cl)+(1-pnorm(cu)))/(0.8*(pnorm(cl)+(1-pnorm(cu)))+p1*(pnorm(cl+3)+(1-pnorm(cu+3)))+(0.2-p1)*(pnorm(cl-4)+(1-pnorm(cu-4))))}-0.05
First fix p1 to be 0.15.
(i) choose a lambda value, say lamda=0.6,

[sm.density.compare] scale up y-axis and additional line type
Dear fellows,
The two questions are on sm.density.compare(). I compare kernel density
estimates of two arrays of data.
I'd like to scale up y-axis so that I can show better the differences in
y values. English is not my first language so I'll try to explain it. I
would like to stretch y-axis a bit longer but not to change the range of
y values. How can I do this?
Second, I'm

consolidate three function into one
Hi Bert,
I am sorry to bother you on weekend.
I am still struggling on defining a correct function.
I first defined the function RFS (see below), then run it by provide the two argument.
m52.2cluster <-RFS(inputfile =allinfo_m52, N=2 )
I do not get error message, but no figure displays on screen. I do not know what is going on.
Can you help me a little more on this issue?
Thank you,

legend in R plot
Hi all,
I am have some difficulty with the legend function.
I need to add a legend to describe the different line types in a plot. The
legend box is small.
It did not include sufficient length of each line type to help distinguish
the differnt line types.
Is there a way to fix this.
Thank you

Accessing more than two coefficients in a plot
I've successfully plotted (in the plot and abline code below) a simple regression of Lambda1_2 on VV1_2. I then successfully regressed Lambda1_2 on VV1_2, VV1_22 and VV1_212 producing lm2.l. When I go to plot lm2.l using abline I get the warning:
"1: In abline(lm2.l, col = "brown", lty = "dotted", lwd = 2) : only using the first two of 4 regression coefficients"

Hi Richard,
Thank you so much!! I understand the problem now, I assign a name to the "ggsurvplot" object and then add print(fig) at bottom of function definition, now figure gets printed on screen.

thick plot lines
Dear People,
In a qqplot I am doing, I get lines/points that are very thick. I've tried
setting the lwd variable to 0.1, but it doesn't seem to have any effect.
Also, I have set the value of lty to dashed, but I still get dots. The
command looks like
qqplot(cdf.inv(seq(0,1,length=size),theta,pos,len),empmargdistvec(len,theta,pos,size),
xlim=c(-theta,theta), ylim=c(-theta,theta),

no y-axis
HI @ all,
I'm looking for a simple solution to supress the y-axis - but only the drawn
scale - not the values.
Only the numbers should be displayed.
I tried yaxt="n" but there everything of the y-axis is supressed.
Thanks

Help with Plot/Legend
Dear R-Users
I have 2 questions:
Firstly, If I create a matplot and legend for multiple vectors and then tag
another vector on using matlines (e.g. a 'total' of all vectors), is there
anyway to add the new line to the legend without recreating it? I have
created the plot this way because I would like to define the lty and lwd for
the 'total' vector so that it can be

optimal control, maximization with several variables?
Dear all,
I would like to solve the following problem, which can be done with optimal control theory or dynamic programming:
max(x,y) a*u1+b*u2+c*f1(u2) s.t. 0<u1<x, 0<u2<f2(x,u2), x'=f3(u1,u2,x)
which can be rewritten if optimal control theory should be applied as
H=a*u1+b*u2+c*f1(u2)+lambda*(x') s.t. 0<u1<x, 0<u2<f2(x,u2)

Help with constrained optimization
Dear all,
I need an advice in the following problem.
I have to maximize two functions of the form f1(x)=f(y1,x,alpha1,beta1) and f2(x)=(y2,x,alpha2,beta2), the maximization is with respect to alpha1, alpha2, beta1, beta2. I can maximize each function separately using nlm.
The problem is that I have to add the constraint of the form g(alpha1)=g(alpha2).
The total number of parameters is
